------------------------------------------------------------------ Section 1 ---------------------------------------------------------------- Joist Trak™ Heat-Transfer Panel Overview Introduction Joist Trak™ heat-transfer panels provide fast and effective installation of radiant heat in virtually every application (floors, walls and ceilings). The rigid channel construction makes it easier for flexible hePEX™ plus tubing to be snapped into place tightly and securely.
--------------------------------------------------Section 2 ------------------------------------------------------------------ Filler Boards Joist Trak Heat-Transfer Panel Specifications When installing Joist Trak panels to the face of a wall or ceiling, it is necessary to provide ⁵⁄₈-inch thick filler boards between the channels of the Trak panels (⁵⁄₈-inch sheetrock is commonly used). For 8-inch on-center wall spacing, use 7-inch wide filler boards.
------------------------------------------------------------ Section 4 ------------------------------------------------------------------ Joist Trak Heat-Transfer Panel Installation Joist Trak Installation Install the Joist Trak panels with either screws or nails into the prepunched mounting holes. If available, a power nailer or screw gun helps facilitate the installation process. Install the panels with a minimum ¹⁄₄-inch gap between them to allow for expansion and contraction.
Joist Trak is available for either ³⁄₈" or ¹⁄₂" tubing. Larger tubing is not used due to the common space constraints when working within joist bays. Wirsbo recommends ³⁄₈" Joist Trak panels for installations below the subfloor and other space-constrained applications. Use ³⁄₈" Joist Trak panels for wall and ceiling applications as well. Step 4 Determine the System Supply-Water Temperature Use the Joist Trak Water Temperature Chart (below) to determine the system supply-water temperature. 1.
